Extreme Pro v2 SSD - Secure Wipe / Sanitize on MacOS?

Hi, how do I secure wipe the latest Extreme Pro SSD v2 4TB variant?

  1. The official GUI software doesn’t seem to be on MacOS. Please correct me if I’m wrong. I understand that there’s a very efficient TRIM command that is vendor specific that can be used to wipe the drive without degrading its life.
    I also understand that HDD-based wiping methods of overwriting don’t really work on SSDs as mentioned here https://apple.stackexchange.com/questions/258170/how-to-get-the-securely-erase-function-of-disk-utility-on-el-capitan-sierra

1b. I tested deleting 1TiB of files from the drive from Finder, then emptying trash and then scanning the drive with R-Studio and R-studio was successfully able to recover all the files…

  1. What’s the differenc between Sanitize and Secure Wipe in Sandisk’s parlance?


Hi @graveldisk,

Please refer to the formatting of a drive using a Mac OS:

Secure Erase is different from Sanitize because it only deletes the mapping table but will not erase all blocks that have been written to. Sanitize will delete the mapping table and will erase all blocks that have been written to. Therefore, Secure Erase is faster to complete than Sanitize. After you erase the drive using Secure Erase or Sanitize, all user data will be permanently destroyed on the selected drive. This data cannot be recovered.

Thanks @Keerti_01

I did that Disk Utility method but R-Studio was able to recover all the files.
Is there a way to do Secure Wipe or Sanitize on Mac?
